What is meant by Chronopotentiometry?

By the term chronopotentiometry we mean an electrochemical technique in which a controlled current, usually a constant current, is caused to flow between two electrodes; the potential of one electrode is monitored as a function of time with respect to a suitable reference electrode.

What is the use of chronopotentiometry?

Chronopotentiometry is used to study mechanism and kinetics of chemical reactions. In this technique, the instrument operates in galvanostatic mode to control current and measure voltage. The applied current can consist of either a single or double step. It is generally performed in a quiet (unstirred) solution.

What is the difference between Chronopotentiometry and chronoamperometry?

is that chronoamperometry is (physics|analytical chemistry) an analytical technique in which an electric current is measured during the course of a titration while chronopotentiometry is (chemistry|physics) a form of electroanalysis in which the rate of change of potential at an electrode is measured at constant …

What is the principle of chronoamperometry?

Chronoamperometry is an electrochemical technique in which the potential of the working electrode is stepped and the resulting current from faradaic processes occurring at the electrode (caused by the potential step) is monitored as a function of time.

What is Galvanostatic condition?

Galvanostatic refers to an experimental technique whereby an electrode is maintained at a constant current in an electrolyte. This technique is used to measure corrosion rate and electrochemical reactions.

What is faradaic and non faradaic process?

Both Faradaic and non-Faradaic processes can take place at an electrode. Thus, in a Faradaic process, after applying a constant current, the electrode charge, voltage and composition go to constant values. Instead, in a non-Faradaic (capacitive) process, charge is progressively stored.

What is potentiostatic method?

Potentiostatic, like galvanostatic and potentiodynamic, is a polarization technique that allows for the controlled polarization of metal surfaces in electrolytes, in order to observe cathodic and anodic behaviors. Potentiostatic techniques can be used in: Corrosion product identification and analysis.

Why is chronoamperometry used?

Chronoamperometry is used to study the kinetics of chemical reactions, diffusion processes, and adsorption. In this technique, a potential step is applied to the electrode and the resulting current vs. time is observed. The chronoamperometry experiment can also be used to monitor or detect events.

Why do we use 3 electrodes in voltammetry?

In order to apply potential, we require some standard/reference electrode, whose potential is almost constant. So we have to avoid using this RE as current carrying electrode. So we require a third electrode called Counter or Auxiallry electrode and its main purpose is to complete the circuit to carry current.

What is the function of potentiostat?

A potentiostat (Figure 1) is an electronic instrument that controls the voltage difference between a Working Electrode and a Reference Electrode. Both electrodes are contained in an electrochemical cell.
